BAIL-ANCHOR.

Specification of Letters Patent.

Patented May 24:, 1921.

Application filed. September 14, 1920. Serial No. 410,288.

To all whom it may concern:

Be it known that I, LAURENCE J .Bmuzn- I LEY, a citizen of the United States residing at Milwaukee, in the county of and State of Wisconsin, have invented certain new and useful Improvements in Rail- Anchors, of which the following is a specification.

My invention relates to rail anchors, and has for its object to provide an improved device of this-character which may be conveniently applied to the base flange of a rail, which will maintain a firm initial grip, and which will increase its grip transgersely of the rail when the rail is subjected to a creeping pressure.

A more specific object of the invention is to provide a rail anchor of the two-piece type, consisting of a yoke member and a tieabutting member which have an interlocking engagement with each other, and which together embrace the base flange of the rail. One of said members, preferably the tieabutting member, is made of springmetal and so bent that the anchor device as a whole will normally grip the opposite edges of the railbase with spring pressure, and said member will be flexed during the presence of a creeping pressure on the rail, to produce an increased gripping action transversely of the rail, and also take a firm shackle hold on the rail base.

The invention has for further objects the novel arrangements and construction of the parts and devices, hereinafter described and Fig. 3 is a view, in perspective, of the tieabutting member before the same is bent to the shape in which it is illustrated in the preceding figures; and i Fig. 4 is a view in perspective of the yoke member Milwaukee Like characters of reference designate like parts in the several figures of the drawing.

Referring to the drawing, 10 designates a railroad rail, and 11 one of the cross ties on which the rail is supported. The rail anchor illustrated in the drawing consists, preferably, of a sheet metal yoke 12 formed at one end with a jaw 13 which fits over one edge of the base flange of the rail, and formed at its other end with a hook shaped portion 14 which interlocks with a spring metal jaw member 15 adapted to grip the opposite edge of the rail base when the device is in its applied position. The spring metal jaw member 15 is formed from a blank 16, shown in Fig. 3,'by bending the blank on the line a-a until the ends 17, 18 stand at an acute angle with relation to the edge of the rail base. this member are formed with recesses 19, 20 providing jaws which fit over the edge of the base flange of the rail at points on opposite sides of the yoke. The ends 17, 18 have such an angular position with relation to the length of the rail that the inner vertical edges 21, 21 of the jaws 19, 20 take a biting, shackle hold on the vertical edge 22 of the rail base when the rail is subjected to a creeping pressure. The spring jaw member is provided with a flange 23 which is curved inwardly and bears against one of the vvertical faces of the tie 11 when the anchor is in its applied position, as shown in Fig. 1. The central portion of the spring jaw member is slotted, as indicated at 24, which slot receives the lower portion of the yoke 12 and holds it in a vertical position. When the spring jaw member is bent to the form shown in Figs. 1 and 2, the apex of the bend inclines downwardly toward the rail base, thus providing a cam surface 25 over which the lip 26 of the hook end of the yoke rides when the yoke is elevated from the positlon shown in Fig. 2 to its operative posltion. The inner edges 27, 28 of the hook 14 and lip 26 are preferably formed with tapers corresponding to the said inclinatlon of the spring yoke member.

In operation, the spring yoke member 15 is first applied to one edge of the rail base with its flan e 23 abutting against one of the vertical aces of the tie. The jaw end 13 of the yoke 12 is then fitted over the op osite edge of therail base and the hook @115. 14 elevated unt l it enters the slot 24 The ends 17, 18 of I 1 over the spring jaw of the spring jaw member 15. As the hook end 14 of the yoke is further elevated, the ends 17 18 of the spring jaw member will spread sufficiently to permit the lip 26 of the yoke to snap over the upper edge of the spring jaw member, thereby interlocking these members in their applied position. By forcing'the hook end of the yoke member in this manner, the spring jaw member is tensioned so as to exert an initial spring grip on opposite edges of the rail base, the length and angularity of the ends 17, 18 of the spring jaw member being such as will permit the application of the device to rails having different widths without danger of subjecting the spring jaw to too much tension or impairing its adaptability to take a firm shackle hold on the rail. During the presence of a creeping pressure, tending to move the rail longitudinally in the direction indicated by the arrow in Fig. 1, the jaw 19 will take a biting hold on the rail so as to move with it, while the jaw 20 is held stationary by reason of the flange 23 bearing against the tie. This produces a bending action at the apex of the bend 29 of the spring jaw member (Fig. 1) and thereby moves the yoke in the direction of its length to increase the grip of the device transversely of the rail. In addition to the above mentioned transverse gripping action it will be noted that the creeping movement of the rail will produce an increased shackle hold of the jaws 19, 20 on the vertical edge 22 of the base flange.

I claim:
